Hi,
According to the network guy the multicast is all there, but we've got no step further, so we're trying your suggested method now :)
Didn't know that corosync now supports unicast too, must've missed that...
Thanks for the heads up!

Or use upnp ... unicasts if you don't want/can change your network setup
